Inclusion Criteria:

• Body Mass Index between 18.5 and 30.0 kg/m2.

Exclusion Criteria:

• Known or suspected hypersensitivity to tamsulosin HCl, solifenacin succinate, EC905 or any of the components of the formulations used.
• Any of the liver function tests above the upper limit of normal at repeated measurements.
• Any clinically significant history of asthma, eczema, any other allergic condition or previous severe hypersensitivity to any other drug (excluding non-active hay fever).
• Subject is at risk of urinary retention based on medical history.
• A planned cataract surgery within 30 days after completion of the study.
• Any clinically significant abnormality following the investigator's review of the pre-study physical examination, ECG and clinical laboratory tests.
• Abnormal pulse rate and/or blood pressure measurements at the pre-study visit as follows: pulse rate <40 or >90 bpm; mean systolic blood pressure >160 mmHg; mean diastolic blood pressure >100 mmHg (blood pressure measurements taken in triplicate after subject has been resting in supine position for 5 min; pulse will be measured automatically).
• A marked baseline prolongation of QT/QTc interval after repeated measurements of 450 ms, a history of unexplained syncope, cardiac arrest, unexplained cardiac arrhythmias or torsades de pointes, structural heart disease, or a family history of Long QT Syndrome (LQTS).
• Use of any prescribed or OTC (over-the counter) drugs (including vitamins, natural and herbal remedies, e.g. St. John's wort) in the 2 weeks prior to admission to the Clinical Unit, except for occasional use of paracetamol (up to 3 g/day).
• Regular use of any inducer of liver metabolism (e.g. barbiturates, rifampin) in the 3 months prior to admission to the Clinical Unit.
• Any use of drugs of abuse within 3 months prior to admission to the Clinical Unit.
• History of smoking more than 10 cigarettes (or equivalent amount of tobacco) per day within 3 months prior to admission to the Clinical Unit.
• History of drinking more than 21 units of alcohol per week (1 unit = 270 cc of beer or 40 cc of spirits or 1 glass of wine) within 3 months prior to admission to the Clinical Unit.
• Donation of blood or blood products within 3 months prior to admission to the Clinical Unit.
• Positive serology test for HBsAg, anti HAV (IgM), anti-HCV or anti-HIV 1+2.
• Participation in any clinical study within 3 months or participation in more than 3 clinical studies within 12 months, prior to the expected date of enrolment into the study, provided that the clinical study did not entail a biological compound with a long terminal half-life. An exception is (partly) participation in Astellas study 905-CL-071, provided a washout of at least 12 days is considered prior to re-enrolment.
• Employee of the Astellas Group or CRO involved in the study.
